Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional terms such as "inner" and "outer" refers to the inner and outer of the relevant component parts, unless otherwise indicated.

As shown in fig. 1 to 8, according to an aspect of the present disclosure, a tire 10 of a vehicle wheel is provided, and an electric heating material layer 20 is disposed inside the tire 10 for heating a tread of the tire 10, mainly for heating a crown rubber layer 111 of the tire 10 to achieve a warming effect.

By arranging the electric heating material layer 20, when the tire 10 needs to be heated, the electric heating material layer 20 can be supplied with electric energy by using a vehicle-mounted power supply or a separate power supply, and the electric energy is converted into heat energy through the electric heating material layer 20 to indirectly heat the tread of the tire 10 by using a wired or wireless technology.

In contrast to the prior art in which the tire can only be heated by a runflat, in the tire 10 provided by the present disclosure, no runflat is required, and the tread of the tire 10 can be actively heated in situ while the vehicle is stationary. Like this, when using in the match, before not starting, can heat tire 10 in advance through electric heat material layer 20, warm the child, obtain better warm child effect for tire 10 obtains the temperature of ideal, thereby obtains better land fertility of grabbing, makes the cycle racing travel more stably safer, also enables to cross the turn more smoothly, and it is faster to go out the turn speed, reduces the phenomenon of skidding, is favorable to promoting the match score. When the tire is applied to low-temperature environments such as ice, snow and the like, the tire can be quickly warmed through the electric heating material layer 20, so that the frozen tire tread is quickly melted, and the protective performance and the like of the tire 10 are improved.

In addition, when the tread of the tire 10 is not required to be heated or the continuous heating of the tread is required to be stopped, the electric energy supplied to the electric heating material layer 20 can be cut off according to the requirement so as to cut off the heating work of the electric heating material layer 20 on the tread, so that the temperature of the tread of the tire 10 can be always kept within the ideal range.

As can be seen from the above, the tire 10 of the wheel 100 according to the present disclosure is advantageous for expanding the range of use of the four-season tire and the summer tire, and particularly, when used for a snow tire, can improve the performances such as the wear resistance of the snow tire.

The present disclosure does not limit the heating material used for the electric heating material layer 20. In one embodiment of the present disclosure, the heat generating material of the electric heating material layer 20 may be made of graphite. In other aspects of the present disclosure, the electric heating material layer 20 may be made of a heat-generating alloy or the like.

Further, the present disclosure does not limit the mounting position of the electric heating material layer 20 on the tire 10 as long as the electric heating material layer 20 can achieve heating of the tread of the tire 10. In one embodiment of the present disclosure, optionally, as shown in fig. 2 and 3, the electric heating material layer 20 may be disposed between the crown rubber layer 111 and the belt layer 113 of the tire 10, and a first conductive adhesive layer 112 is disposed between the crown rubber layer 111 and the electric heating material layer 20 of the tire 10, the first conductive adhesive layer 112 is electrically connected to the electric heating material layer 20 to conduct electricity to the electric heating material layer 20, and the first conductive adhesive layer 112 partially extends to the outer surface of the crown rubber layer 111.

In this embodiment, the first conductive adhesive layer 112 may be connected to a power source through a connecting structure such as a wire, so as to supply power to the electric heating material layer 20, thereby heating the electric heating material layer 20. Since the first conductive rubber layer 112 partially extends to the outer surface of the crown rubber layer 111, that is, to the outer surface of the tire 10, it can be in contact with the ground. Thus, when the electric heating material layer 20 does not work, the first conductive adhesive layer 112 of the exposed portion can conduct the static electricity of the tire 10 to the ground, so that the tire 10 has a better conductive performance, and the tire 10 is not only a tire 10 capable of being actively heated, but also a tire 10 with excellent conductive performance.

Specifically, the electric heating material layer 20 may be pressed between the crown cap rubber layer 111 and the belt layer 113 of the wheel 100 at the stage of building the tire 10 and fixed inside the tire 10 by, for example, a vulcanization process, that is, the electric heating material layer 20 may be disposed between the crown cap rubber layer 111 and the belt layer 113 of the tire 10 by a building process to reliably dispose the electric heating material layer 20 on the tire 10.

In the present disclosure, the size of the electrocaloric material layer 20 is not limited. In one embodiment, the length of the electric heat material layer 20 is equal to the length of the tread rubber layer 111 in the circumferential direction of the tire 10, that is, the circumference of the electric heat material layer 20 is equal to the circumference of the tread rubber layer 111. Like this, guaranteed that electric heat material layer 20 heats every section of the corresponding child cap face rubber layer 111 in circumference, be favorable to promoting the heating effect. In addition, the ratio of the width of the electrothermal material layer 20 to the width of the crown rubber layer 111 in the width direction of the tire 10 is 1:2 to 3:5, and optionally, the center line of the electrothermal material layer 20 in the width direction is aligned with the center line of the crown rubber layer 111 in the width direction. Generally, since the tread rubber layer 111 has a certain curvature in the width direction and the ground contact width is smaller than the width thereof, the width of the electric heating material layer 20 may be slightly smaller than the width of the tread rubber layer 111. The width ratio can avoid not only the situation that the tread rubber layer 111 cannot be effectively heated due to the fact that the width of the electric heating material layer 20 is too small, but also the situation that the material is wasted due to too large width, and meanwhile, the situation that the width of the electric heating material layer 20 is too large and the interference is formed between the tread of the tire 20 and the arc part (tire shoulder) between the tire sides can be avoided.

In addition, the thickness of the electric heating material layer 20 is optionally 5mm-8mm, so that the material is saved and the heating effect is good.

In one embodiment of the present disclosure, the first conductive rubber layer 112 may be equal in length to the crown cap layer 111 in the circumferential direction of the tire 10, i.e., the circumference of the first conductive rubber layer 112 may be equal to the circumference of the crown cap layer 111. In addition, the first conductive rubber layer 112 may be equal in width to the cap rubber layer 111 in the width direction of the tire 10.

As shown in fig. 2 and 4, in one embodiment of the present disclosure, a second conductive rubber layer 122 may be disposed between the sidewall surface rubber 121 and the carcass ply 13 of the tire 10. Wherein the second conductive adhesive layer 122 can be electrically connected with the electric heating material layer 20, and the second conductive adhesive layer 122 is used for connecting with the rim 30 of the wheel 100. In this way, the rim 30 may be conductively connected to a power source such that current is transmitted to the electrocaloric material layer 20 through the rim 30 and the second conductive glue layer 122 in sequence. An additional lead wire for supplying power to the electric heating material layer 20 can be omitted, which is beneficial to simplifying the structure of the tire 10 and avoiding the influence on the running of the tire 10. In other embodiments of the present disclosure, the first conductive adhesive layer 112 and the second conductive adhesive layer 122 may be an integral structure.

In addition, it should be noted that the transmission path of the current is not limited in the present disclosure, and may be any suitable transmission path, for example, the electric heating material layer 20 may be wirelessly connected with a power source disposed on the wheel 100 or the vehicle body by bluetooth, etc., so that the current can be transmitted to the electric heating material layer 20 even without the second conductive adhesive layer 122.

Alternatively, the first and second conductive gum layers 112, 122 of the present disclosure may be obtained by adding carbon black content to the commonly used base gum for the tire 10, for example, adding carbon black content to the prior art crown base gum 17 as shown in fig. 11 enables it to have a conductive function.

To facilitate monitoring the temperature of the tire 10 to maintain the tire 10 at a desired temperature value, as shown in fig. 2 and 3, in the present disclosure, the tire 10 of the wheel 100 is provided with a temperature sensor 40 for detecting the temperature of the tread of the tire 10.

By providing the temperature sensor 40 on the tire 10 to monitor the temperature thereof and timely turning on and off the electric heating material layer 20 provided on the tire 10 according to the detected value, the tire 10 is prevented from operating at an excessively high temperature or an excessively low temperature (a temperature that does not satisfy the operating requirement). Thus, it may be advantageous to ensure that the temperature of the tire 10 is always maintained within a desired temperature range, based on various circumstances.

Wherein, optionally, the temperature sensor 40 may be disposed on the surface of the inner liner 14 of the tire 10 and located on the central plane of the width direction of the tire 10. That is, the temperature sensor 40 is disposed directly below the tread center line of the tire 10. This arrangement has the advantage of minimizing the effects of non-uniformity in the mass of the wheel 100 caused by the temperature sensor 40 being located on the tyre 10, and of avoiding problems with dynamic balancing of the tyre 10. And since the temperature outside the tire 10 may be approximately equal to the temperature inside the tire 10, the temperature sensor 40 can detect a more accurate temperature value. On the other hand, when the tire 10 and the rim 30 of the wheel 100 are assembled in place, the temperature sensor 40 is located inside the wheel 100, so that the temperature sensor 40 is prevented from being affected by the external environment, and the temperature sensor 40 is protected.

It should be noted that the present disclosure does not limit the installation position of the temperature sensor 40, and besides being disposed on the inner liner 14 of the tire 10, any suitable position of the wheel 100 may be disposed in other embodiments of the present disclosure, for example, integrated between the rubber layers of the tire 10.

The present disclosure is not limited to the specific structure of the tire 10, and in one embodiment, as shown in fig. 3, the tire 10 may have a tread rubber layer 111, a first conductive rubber layer 112 (i.e., a tread base rubber layer), an electrothermal material layer 20, two belt layers 113 and an inner liner layer 14 in sequence from the outside to the inside of the tread 11. As shown in fig. 4, the tire 10 may have, in order from the outside to the inside, a sidewall rubber layer 121, a second conductive rubber layer 122 (i.e., a sidewall primer layer), two carcass plies 13, and an inner liner 14. That is, the crown 11 and sidewalls 12 of the tire 10 may have a common two-layer carcass ply 13 and liner 14, and the cap ply 111 of the crown 11 may be in contact with the side ply 121 of the sidewalls 12.

In the present embodiment, when the electric heating material layer 20 is operated, as shown in fig. 5, the current path of the tire 10 may be: the second conductive rubber layer 122 (electrically connected to the rim 30 of the wheel 100) → the belt layer 113 of the sidewalls 12 → the electric heating material layer 20, thereby supplying electricity to the electric heating material layer 20. When the electric heating material layer 20 does not work, the static electricity of the tire 10 can be conducted to the ground through the first conductive adhesive layer 112, so that the static electricity of the tire 10 can be discharged.

As shown in fig. 5 and 11, the first conductive rubber layer 112 (i.e., the tread cap base rubber layer) of the tire 10 provided by the present disclosure is made of a rubber compound with high conductivity and extends to the center of the tread, so as to facilitate conducting static electricity to the ground. As shown in fig. 6 and 12, the sidewall 12 of the tire 10 of the present disclosure is added with a second conductive adhesive layer 122 (i.e., sidewall primer) capable of conducting electricity, and the second conductive adhesive layer 122 can transmit the current to the electric heating material layer 20.

As shown in fig. 7, according to another aspect of the present disclosure, a wheel 100 is provided, which wheel 100 may include the tire 10 described above. Wherein the rim 30 of the wheel 100 can be electrically connected with the electric heating material layer 20 for electrically connecting to the electric heating material layer 20. As discussed above, other conductive paths may be formed on the wheel 100, such as electrically connecting the electric heating material layer 20 to a power supply through a wire.

As shown in fig. 9, according to yet another aspect of the present disclosure, a vehicle is provided that includes the wheel 100 described above.

Alternatively, the vehicle includes a controller (not shown), a relay (not shown) and a temperature sensor 40 for detecting the temperature of the tread of the tire 10, the relay is electrically connected to the electric heating material layer 20, and the controller controls the on/off of the current of the electric heating material layer 20 through the relay according to the detection result of the temperature sensor 40. In this way, the controller, the relay, the temperature sensor 40, the rim 30 of the wheel 100, the conductive adhesive layer, and the like form a temperature control system for controlling the temperature of the electric heating material layer 20, and the current of the electric heating material layer 20 is controlled to be timely turned on or off, so that the temperature of the tire 10 is actively adjusted in time. And when the electric heating material layer 20 does not work, the static electricity in the tire 10 can be conducted to the ground through the first conductive adhesive layer 112. Optionally, the vehicle further includes a temperature-controlled switch (not shown), and the controller controls the opening and closing of the temperature-controlled switch according to the detection result of the temperature sensor 40, so as to control the armature of the relay to contact or separate, and thus control the on/off of the current.

The present disclosure does not limit the location of the relay and the controller on the vehicle, and may be any suitable place, for example, the controller may be integrated into an ECU controller of the vehicle. The relay may be provided on the vehicle body.

As shown in fig. 9, in one embodiment of the present disclosure, the vehicle may also be provided with an infrared thermal detector 50 for detecting the temperature and wear of the tread of the tire 10.

Alternatively, as shown in fig. 9 and 10, the infrared thermoscope 50 may be fixed (e.g., bonded or screwed, etc.) to the lower surface of the wheel house 200 to detect the difference in height between the top of the block 15 and the bottom of the groove 16 of the tire 10. Thus, in the present embodiment, the infrared temperature detector is not affected by the deformation of the tire 10, so that the temperature change of the tread can be monitored more accurately, which is beneficial to timely controlling the discharge and power off of the tire 10, and the purpose of intelligently controlling the temperature of the tread of the tire 10 is achieved. Further, since the infrared temperature detector 50 is provided in the vehicle body, the movement of the wheel 100 is not affected, for example, the dynamic balance of the tire 10 is not affected, and thus the problem of the running of the wheel 100 being shaken due to the provision of the infrared temperature detector 50 does not occur.

In the present embodiment, the infrared temperature detector 50 may integrate an infrared distance measuring function to monitor the wear of the tire 10 in real time, ensure the timely replacement of the tire 10, and ensure the safety of the vehicle.

Specifically, as shown in FIG. 10, the infrared thermoscope may detect the wear of the tread of the tire 10 by measuring the difference in height of the top of the blocks 15 and the bottom of the grooves 16 of the tire 10. Specifically, the distance H1 from the detection position of the infrared thermal detector 50 to the bottom of the groove 16 of the tire 10 can be measured, the distance H2 from the detection position of the infrared thermal detector 50 to the top of the pattern block 15 of the tire 10 can be measured, and then the difference between the two distances is subtracted, so that the height difference between the top of the pattern block 15 of the tire 10 and the bottom of the groove 16 can be obtained. The abrasion condition of the tire 10 is indirectly monitored in real time by monitoring the groove depth of the tire 10 in real time, and the method is convenient and accurate.

It should be noted that the present disclosure does not limit the position where the infrared temperature detector 50 is disposed on the vehicle body. Hereinafter, the operation principle and process of heating the tire 10 of the wheel 100 according to an embodiment of the present disclosure will be briefly described with reference to the accompanying drawings:

as shown in fig. 7, the vehicle-mounted power supply may be connected to the relay and the rim 30 (e.g. an aluminum wheel) through a wire, and the current is transmitted to the belt layer 113 along the second conductive adhesive layer 122 disposed on the sidewall 12 through the bead portion where the rim 30 contacts the tire, and then the belt layer 113 transmits the current to the electric heating material layer 20 to provide electric energy to the electric heating material layer 20, and the heating medium graphite of the electric heating material layer 20 is electrified to generate heat to convert the electric energy into heat energy, so as to heat the tread (mainly the tread rubber) of the tire 10. When a certain temperature is reached, the temperature sensor 40 attached to the inner side of the tire 10 transmits a signal to the controller, and the controller controls the opening and closing of the temperature control switch according to the signal, so that the armature of the relay is controlled to be in contact or separated, the on-off of current is indirectly controlled, the electric heating material layer 20 works at a low temperature and does not work at a high temperature, and the tread of the tire 10 is kept to work within the most suitable use temperature range all the time. As shown in fig. 8, when the electric heating material layer 20 does not work, the static electricity of the tire 10 can be conducted to the ground through the first conductive adhesive layer 112.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
